RE: physical network port matchup to /etc/sysconfig/network-scripts/ifcfg-eth*



I have an IBM x37 series which has 6 network ports all labelled. The ethx  numbers always  change on reboot . The best way is to  find the mac addresses of each card and lock it in with the corresponding ifcfg-ethx file.
